Managing Pallets

Once pallets are created, they appear in the Items Panel as collapsible groups with amber-colored headers. LOP provides tools to edit, reorder, lock, duplicate, and delete pallets throughout the planning process.

Pallet Groups in the Items Panel

Each pallet appears as a group header showing:

• Pallet name — editable (e.g., "Pallet #1 (EUR)")
• Item count — the number of physical units on the pallet (a quantity item counts once per unit, so 3 units of the same carton show as "3 items")
• Total weight — combined weight of all items
• Capacity % — max(volume%, weight%), whichever constraint is binding
• PALLET badge on the right side, color-tinted by Capacity (green below 90%, amber at 90–100%, red above 100%). Hover the badge to reveal ▲ / ▼ / ✕ quick actions (reorder / delete)

Click the header to expand the group and see the individual items on that pallet. The Edit Pallet panel shows the Capacity % split into two rows: Volume used % and Weight used %.

Editing a Pallet

To modify a pallet's contents or settings:

1. Right-click the pallet header in the Items Panel → select "Edit Pallet"
2. Or double-click the pallet in the 3D viewport

The Palletize Panel opens in edit mode with the title "Edit Pallet" and a "Save Changes" button instead of "Create Pallet". You can:

• Add or remove items from the pallet
• Change the pallet type
• Change the packing pattern or layer rotation
• Re-run Auto-Pack with new settings

Click "Save Changes" to apply your edits.

When Item Dimensions Change

When you change the dimensions of an item that is loaded on a pallet or rack — in the item's edit panel, or in the Item Library (a plan picks the change up the next time it is opened) — LOP resizes every box of that item where it stands. No item is moved. The Items Panel then shows "Item dimensions changed. Check the affected pallets before loading.", and each affected pallet or rack shows its state under its header:

• Review placement — the item's boxes changed size, and none of them overlaps another box or extends past the pallet. Check the positions before loading.
• Re-pack needed — some items now overlap or extend past the pallet (or rack).

The line under the state says why. To resolve it:

• For a pallet, click "Re-pack pallet…". Edit Pallet opens; run Auto-Pack, and LOP shows how many units fit before anything is saved — for example "This changes item positions on Pallet #1. 1 of 12 items fits; 11 will remain loose." "Apply new pallet layout" saves it: units that do not fit come off the pallet and stay in the plan, so the item's quantity never changes. "Keep current positions" closes the panel and changes nothing.
• For a rack, click "Review rack…" to open the rack editor, then move, turn or remove units. A rack is never re-packed by Auto-Pack. The overlap and edge check above compares the item boxes only; it does not include the rack's own frame and shelves.

Saving a pallet's contents clears Review placement. Re-pack needed clears once the saved layout no longer overlaps or extends past the pallet. A locked pallet shows its state but offers no editor until you unlock it.

Locking and Unlocking Pallets

Locking a pallet protects it from accidental changes:

• Right-click the pallet header → "Lock Pallet"
• A lock icon appears on the pallet header

When a pallet is locked:

• It cannot be edited, deleted, or dragged in the viewport
• It is excluded from "Clear existing" when running Palletize All
• It is preserved when running Unpalletize All
• Its drawn horizontal orientation is preserved by Optimize/Solve.
• The cursor shows a pointer (not a grab handle) in the viewport

To unlock: right-click → "Unlock Pallet".

Reordering Pallets

Pallet order determines the loading sequence: the first pallet loads first (placed at the back of the container), the last pallet loads last (nearest the door for first unloading).

To change the order:

• Hover over a pallet header to reveal up/down arrow buttons
• Click the arrows to move the pallet up or down in the list

The container solver respects this order when placing pallets.

Duplicating a Pallet

To create a copy of an existing pallet:

• Right-click the pallet header → "Duplicate Pallet"

A new pallet is created with an auto-incremented numeric suffix on the name (e.g., Bananas → Bananas (1) → Bananas (2)), and the same items, pallet type, and arrangement. The item set is cloned — the duplicate has its own independent items, not shared references to the original's items — and carries the source pallet's full unit composition: if the original holds 3 units of the same carton, the duplicate holds 3 units too.

Deleting a Pallet

Two options for removing a pallet:

Unpalletize (Keep Items)

• Right-click the pallet header → "Unpalletize"
• The pallet is removed but all items return to the unplaced items list
• Items can then be re-palletized or loaded as floor items

Delete Pallet + Items

• Right-click the pallet header → "Delete Pallet + Items"
• The pallet and the units loaded on it are permanently removed from the plan
• For a quantity item whose units are split between this pallet and elsewhere, only the units on this pallet are removed — the item's quantity is reduced accordingly and the remaining units stay in the plan

Unpalletize All

To remove all pallets at once:

• Open the ⋯ overflow menu in the Items Panel header and select "Unpalletize All"
• All unlocked pallets are removed in a single instant step and their items return to the floor
• Locked pallets are preserved
• The plan score refreshes automatically — no re-solve or manual recompute is needed

Next Steps

• Viewport Controls — interact with pallets in the 3D editor
• Manual Palletization — build new pallets
• Pallet Containment — what a pallet holds unwrapped before shipping, and the test that would show the rest
